The Purple Line is a proposed 16-mile light rail transit line project in the Maryland suburbs of Washington, DC inside the Capital Beltway (I-495). Extending between Bethesda in Montgomery County and New Carrollton in Prince George’s County, the new transit line will provide direct connections to four branches of the Washington Metropolitan Transit Authority Metrorail system, as well as all three Maryland Area Regional Commuter rail lines and Amtrak’s Northeast Corridor. The line will have 21 stations and will operate mainly in dedicated lanes, allowing for reliable and rapid east-west service. Having reached financial close in June 2016, the Purple Line became the second ever P3 in the U.S. for a light rail project and the first transportation P3 in the State of Maryland.
